Malgorzata Pietrzykowska has investigated the specific roles of the two most abundant membrane proteins on Earth, Lhcb1 and 2. Both of them are responsible for light harvesting which is the basis of photosynthesis, ...

Replacing fossil fuel investments with "green energy" stocks has minimal impact on reducing greenhouse gas (GHG) emissions, and is also unlikely to provide a safer haven for investors. But with the right policies in place, ...

Earlier this year, Ohio became the first state to freeze a scheduled increase in the amount of electricity that must be generated by wind, solar and other renewable sources. The move gave advocates of repealing states' mandatory ...

A new study by the UK Energy Research Centre (UKERC) suggests that renewable energy and energy efficiency create up to ten times more jobs per unit of electricity generated or saved than fossil fuels. However, in itself labour ...

The way that algae and plants respond to light has been reinterpreted based on results from experiments studying real-time structural changes in green algae. Under particular lighting conditions during photosynthesis, ...

Life in a warming world is going to require human ingenuity to adapt to the new realities of Earth. Greenhouse-gas induced warming and megapolitan expansion are both significant drivers of our warming planet. ...

In the coming years, the Netherlands will have to work hard on Smart Grids, intelligent local networks with new storage capacity for green electricity. It will thus be possible to counter the impending instability ...

Green energy

Green energy is the term used to describe sources of energy that are considered to be environmentally friendly and non-polluting, such as geothermal, wind, solar, and hydro. Sometimes nuclear power is also considered a green energy source. Green energy sources are often considered "green" because they are perceived to lower carbon emissions and create less pollution.

Green energy is commonly thought of in the context of electricity, mechanical power, heating and cogeneration. Consumers, businesses, and organizations may purchase green energy in order to support further development, help reduce the environmental impacts of conventional electricity generation, and increase their nation’s energy independence. Renewable energy certificates (green certificates or green tags) have been one way for consumers and businesses to support green energy.
